How East African Startups Are Solving the Region's Power Problem

More than 360 million people across Eastern and Southern Africa still have no electricity at all, according to the World Bank, and grid connections in the region are being added only slightly faster than the population itself is growing. Extending a national grid to a village of a few hundred people scattered across hilly, low-density terrain rarely makes financial sense for a utility, which is exactly the gap a growing set of East African startups have built entire companies around.

Their answer generally isn't "wait for the grid to arrive." It's smaller, faster, and increasingly digital: solar panels sold on a daily payment plan, mini-grids that skip the national network altogether, and financing models built on the same mobile money rails that already reshaped how the region banks.

Why the Grid Alone Was Never Going to Get There

The economics explain why this problem has persisted for decades despite real investment. Roughly 70% of Kenya's population lives in rural areas where grid extension is expensive per household and revenue per connection is low, a pattern repeated across Uganda and Tanzania. Even where national utilities have expanded generation capacity substantially, Kenya's state-owned KenGen, the region's largest power producer, has more than tripled its geothermal output since the 1980s and continues adding hundreds of megawatts through new Olkaria projects, generation capacity doesn't automatically translate into a wire reaching a specific rural household. That's the gap decentralised, privately built power has stepped into instead.

Pay-As-You-Go Solar Turned a $200 Purchase Into a Daily Habit

M-KOPA, founded in Nairobi in 2011, was one of the first companies to prove this model could work at scale. Rather than asking a rural household to find $200 upfront for a solar home system, roughly a quarter of a household's income where kerosene was the alternative, M-KOPA sells the same system for a small deposit and daily instalments paid through mobile money, using the payment data itself to build a credit profile for each customer. That data has since let the company expand well beyond solar into financing smartphones, appliances, and other assets, backed by debt facilities including a $200 million loan from Standard Bank Group.

Sun King, also Nairobi-based and originally known as Greenlight Planet, has scaled the same basic idea even further. Founded in 2007, the company estimates that nearly 30% of Kenyan homes now use its solar products, and it has sold more than 29 million solar systems and extended over $1.4 billion in consumer solar loans across Africa and Asia. In 2025 alone it closed a $156 million securitisation backed by British International Investment to fund another 1.4 million solar products and smartphones in Kenya, and announced a further $150 million push into Ethiopia. The company is now selling roughly 330,000 solar kits a month and wants to reach one million a month by 2030.

Mini-Grids: Skipping the National Network Entirely

Individual home solar systems solve lighting and phone charging. They don't run a welding machine, a maize mill, or a cold room, the kind of loads a small business actually needs to grow. That's the gap mini-grid developers like PowerGen Renewable Energy are built for.

Founded in Kenya in 2011, PowerGen builds and operates solar-hybrid mini-grids that function as small, standalone power utilities for a village, market centre, or industrial cluster, complete with smart metering and pay-as-you-go billing. The company has installed more than 325 renewable energy systems across a dozen countries, and closed a $50 million funding round to build out 120 megawatts of mini-grid and battery storage capacity aimed at connecting 68,000 households and 7,000 businesses. Independent research from the Kenya Renewable Energy Association has found that household incomes rise by an average of 27% within a year of a mini-grid connection, largely because businesses can simply stay open later.

Uganda's Answer: Mini-Grids Bundled With Public Services

Kenya isn't the only market where this model is taking shape. Equatorial Power, based in Kampala, has built mini-grids across Uganda, Rwanda, Tanzania, and the Democratic Republic of Congo, but its more distinctive approach has been bundling electricity with the services people actually need it for. In a joint venture with Engie Energy Access, the company commissioned a 600 kWp solar mini-grid on Uganda's Lolwe Island in Lake Victoria, explicitly framing electricity as a means to unlock clean water access and agribusiness rather than an end in itself. More recently, it partnered with Germany's GIZ to solarise 27 rural health clinics in Uganda's West Nile region, pairing solar generation with battery storage to keep vaccine refrigeration and basic medical equipment running.

Uganda has real ambitions here: the country's Vision 2040 development plan targets 100% electricity access by 2040, up from roughly 57% today, and its government has explicitly identified locally generated, off-grid solar as the most realistic path to get there, rather than betting solely on extending the national grid. That's a tacit admission from the government itself that companies like Equatorial Power, not just state utilities, will need to carry a meaningful share of the load.

Why This Now Overlaps With East Africa's Climate Tech Boom

Solving the power problem isn't happening in isolation from the rest of the region's technology sector, it's increasingly feeding it. Electric vehicle manufacturers like Roam and BasiGo, which we covered in 5 Investment Themes That Could Define East African Tech in 2027, need reliable charging infrastructure to function at scale, which only works if the underlying power supply is dependable in the first place. The same logic applies to the cloud and AI infrastructure we explored in Why Investors Are Betting on East Africa's Invisible Technology: data centres are power-hungry by nature, and their growth in the region depends directly on how quickly generation and grid capacity keep up.

The Honest Caveat Investors Should Know

None of this comes without real trade-offs. Financing costs for pay-as-you-go solar remain high, with average lending rates of 10 to 20% or more passed through to customers in several African markets, and researchers at the Energy for Growth Hub have argued this creates a "poverty premium" that can leave the very poorest households still priced out even of a $35 deposit. Mini-grid developers, meanwhile, face their own friction: regulatory licensing in Kenya can take up to six months, and only a minority of proposed mini-grid projects currently secure adequate funding to get built at all. Solving East Africa's power problem is happening, visibly and at real scale, but it's happening unevenly, and the companies closest to true universal access will likely be the ones that figure out how to bring financing costs down as much as they bring electricity in.
